If, by saying "go off", you mean that a gfci switches off the supply of electricity, the reason is that it has been made to do this whenever there is:

  • a fault, either in the wiring from it to other socket outlets, or
  • a fault in the wiring to any appliance that is plugged into one of them, or
  • a fault actually inside one of these appliances.

If any GFCI does not reset when you press its 'Reset' button then you will have to find out:

  • where the fault is and
  • get it fixed.

Only after a fault has been fixed will the GFCI reset when you press its 'Reset' button. Then all outlets and appliances connected to it will once again receive a supply of electricity.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

Why would a car alarm go off out of no where if nobody is even touching it?

A car alarm can go off with no one even near it. A bad earthing point or voltage change can make it go off. The sensor on the alarm itself may be too high which will cause it to go off with the lightest of touch.

Can a gfci go bad?

Most definitely. GFCI receptacles have a test buton, and should be tested regularly. you can also buy inexpensive plug-in testers at most home centers and electric supply houses.


When a GFCI senses a fault the ground-fault current can originate from what either the hot or neutral wire on the line side of the GFCI either the hot or neutral wire on the load side of the GFCI?

In a very real sense, a "ground fault" cannot come from the neutral side, since, if your wiring is performing as designed, there should be little potential between the neutral and ground. A ground fault is said to occur when the current OUT, through the "hot" side is not equal to the current BACK, through the neutral, meaning that current is leaking to somewhere else... such as through your body. Having said all that, it is certainly possible that you could cause a GFCI to trip by introducing current to the neutral from a circuit that does not go through the GFCI breaker; but that would involve non-standard wiring practices.
